SP-163 / NBR
SP-163 is polyurethane board for master modeling and exhibits superior surface roughness, easy machinable, good dimensional stability product. As it is also expandable type of board, uniformity of the cell structure contributes to deformation resistance during machining process. As well as SP-150, low dust emission board thanks to characteristics of polyurethane mophology with no odour.
